Common NameIsovitexin
Description5,7-dihydroxy-2-(4-hydroxyphenyl)-6-[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-4H-chromen-4-one belongs to the class of organic compounds known as n-acyl amines. N-acyl amines are compounds containing a fatty acid moiety linked to an amine group through an ester linkage. Based on a literature review very few articles have been published on 5,7-dihydroxy-2-(4-hydroxyphenyl)-6-[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-4H-chromen-4-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isovitexin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Isovitexin is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
